When is the Time to Replace HVAC System

When Is The Right Time to Replace HVAC System? Furnaces and Air Conditioners are Designed for Comfort, But for How Long?

Your home furnace and air conditioner are designed to keep you comfortable during the hottest Las Vegas Summer days and the coolest Las Vegas Winter nights. However, for most people their furnace and air conditioner are hidden in a place (garage or attic) “out of sight, out of mind” and therefore easy to forget. We assume they will continue working because they have worked for months or even years without much attention. How can you know when it’s time to replace your home’s furnace or air conditioner?

1) The Crisis Method of Predicting the Life of Your Furnace or Air Conditioner

Wait until your furnace or air conditioner breaks down.

Here’s the scenario you might expect: Your house is suddenly freezing some Winter night or boiling some Summer day.

DIY Attempts to Fix the Issue

First, you play around with the thermostat settings. Nothing! Then you locate your furnace or air conditioner. Dig through storage to locate a ladder to get into the crawl space in your closet ceiling. Then clear a space for the ladder. Hopefully you can find a flashlight to light your way once you emerge into your attic. Remember, you’re either boiling hot or so cold you can hardly work your hands. You finally manage to locate the furnace or air conditioner, digging through items stacked up in the way. If you’re lucky, you locate the settings and trip a switch thinking it just needs a restart. Nothing!

Calling In a Professional for Emergency Service

Okay, now you know you need to call in a professional. However, it’s likely a Friday evening right before a holiday weekend! Emergency service may not be coming tonight! You make a run to the department store to invest in a space heater or portable air conditioning unit or a huge fan to tide you over until professional service arrives. When the professional does arrive, they may not be able to fix your air conditioner or furnace on the spot but have to order parts. Another few days of waiting in freezing or boiling hot indoor temperatures! In an extreme situation you may even need to move to a motel or a friend or relative’s house for a few days. Imagine what your family members are thinking of you at this moment! So much for the crisis method of how to know when it’s time to replace your home’s furnace or air conditioner.

2) The Guesswork Method of Predicting When Your Furnace or Air Conditioner’s Life May End:

Try to Guess the Life of Your Furnace or Air Conditioner

This is better than the crisis method. You may avert an emergency breakdown of your home’s air conditioner or furnace with the guesswork method. It goes something like this: You reason that most warranties cover 10 years. Why? Because the smart warranty people figure that your air conditioner or furnace will work relatively problem free for about 10 years before things begin to break down.

Schedule Professional Maintenance Near the End of the 10-Year Warranty Period

You call a professional in for a thorough maintenance visit between year’s 9 and 10. If you’re lucky your air conditioner or furnace did not break down earlier. The professional performs maintenance that extends the life of your air conditioner or furnace a few more years. In addition, they might be able to predict how many years your air conditioner or furnace have left before they need to be replaced. You beat the odds and avoided an emergency breakdown, perhaps extending the life of your air conditioner or furnace a few years.

3) The Proactive Method of Knowing When Your Furnace or Air Conditioner Might Break Down

Schedule regular maintenance.

You have a professional perform regular maintenance at least annually thereby extending the life of your home’s air conditioner or furnace, potentially up to 10 additional years giving you 20 years in all. At the same time, your professional may be able to more accurately predict within a few months to a year when it’s time to give in and replace your furnace or air conditioner.
